Why Pickling and Passivation are Crucial for Defence & Aerospace

In Defence & Aerospace applications, even the smallest imperfections in metal surfaces can lead to significant operational issues.

Exposure to harsh environments, such as high altitudes, extreme temperatures, and corrosive agents, can compromise the integrity of metal components.

Pickling and passivation are essential for maintaining the performance and longevity of stainless steel and other alloyed materials. Key benefits include:

  • Removal of Surface Contaminants:
    Our pickling process effectively eliminates scale, rust, and other impurities that can weaken metal surfaces.

  • Improved Corrosion Resistance:
    Passivation creates a protective chromium-oxide layer, enhancing the metal’s resistance to corrosion and oxidation.

  • Enhanced Durability and Performance:
    By ensuring a clean, passive surface, our treatments help components withstand the rigors of defence and aerospace applications, reducing the risk of failure and extending their operational life.

Metapic’s Expertise in Defence & Aerospace Metal Treatment

At Metapic, we understand the critical role that metal treatment plays in the Defence & Aerospace industry. Our facility is equipped with state-of-the-art pickling tanks and advanced passivation technology, enabling us to handle complex components with precision and care.

Our processes are carried out in compliance with internationally recognised standards, such as ASTM A380 and A967, ensuring that every component meets the highest quality and safety criteria.

Our Process Includes:

  1. Detailed Inspection and Preparation:
    We begin by thoroughly inspecting each component to assess its condition and determine the most appropriate treatment approach. A preliminary cleaning is performed to remove any grease, oil, or surface contaminants, preparing the metal for effective pickling and passivation.

  2. Precision Immersion Pickling:
    Components are fully immersed in our specialised pickling solution, allowing the acid to penetrate every surface, including intricate geometries and internal passages. This process removes any scale, rust, or oxide layers, restoring the metal to its optimal
